Thank you for your advice
Meanwhile I watched some videos on youtube
I will buy low temperature soldering paste 138¡ãC. This will also be used for other components and future constructions.. This seems much easier to use with hot air than with soldering iron.
Also as JLCPCB provided at least 5 pcb¡¯s (there I received 6!) and I have more filters prevu, I will be able to train.
there is always a hole on the "Ground" tracks on the PCB footprint for each filter, which will facilitate welding. The connection can be tested at the ohmeter on tracks going to? ?1-2 and 5-6 because there is an impedance to be sure.
Have a good day
